Bathroom after IUI

Had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> today! They told me to drink 24-32ounces of water so my bladder would be full - well I had to pee SO, SO bad I hardly could wait ten minutes after the procedure ! My DH says it was 10 minutes but I don’t know ... you think it’s ok to urinate so soon after? Any success stories ?!
